AWNING.

SPECIFICATION forming part of Letters Patent N 0. 732,739, dated July 7,1903.

Application filed March 16, 1903.

To all whom it may concern:

Be it known that I, CHARLES H. HANSEN, a citizen of the United States,and a resident of Racine, in the county of Racine and State ofWinconsin, have invented certain new and useful Improvementsin Awnings;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates especially to an awning-frame and its joints; andit consists in certain peculiarities of construction and combination ofparts, as will be fully set forth hereinafter in connection with theaccompanying drawings and subsequently claimed. In the said drawings,Figure 1 is a View in side elevation of one of my jointed frames (ofwhich there are two for each awning) in the lowered position; and Fig. 2is a like view of the same in the raised position, portions beingremoved or shown broken away or in section in both figures to betterillustrate certain details. Fig.,3 is a detail sectional view taken onthe line 3 3 of Fig. 1, and Fig. 4 is a like view taken on the line 4 4of Fig. 2.

Referring by numerals to the drawings, 1 indicates the outer wall of abuilding, to which the upper end of an awning 2' is permanentlyattached, as by-nails or screws 3 3, the lower end of said awning beingsecured to a rod 4, which extends between the outer ends of the longsections 5 of my awningframe, only one side of which is shown, the otherside being an exact duplicate thereof and the two sides being separatedthe width of the awning employed. The inner ends of these long sections5 terminate in toothed sector-plates 6, which mesh with correspondingtoothed sector-plates 7at the adjacent ends of the short sections 8 ofthe frame. These short sections 8 are, in effect, bellcrank levers,having arms 9 at their inner ends, and are pivotally secured bypivotbolts 10 to brackets 11, which latter are fastened to thebuilding-wall 1. The-sectorplates 6 7 are pivotally connected by doublelinks 12 12, (one on each side of said sectorplates,) whose ends areunited by bolts 13 13, passing through holes in said sector-plates. Thesector-plate 6 is further formed with another hole therethrough for thepivot-bolt 14, on which are mounted the lower ends of Serial NO.147,877. (No model.)

three double straps, marked 15 15, 16 16,

and l7 17, respectively,) the forward ends of these three double strapsbeing respectively united by the bolts 18, 19, and 20. From the bolt 18,which unites the outer ends of the double strap 15 15, a spring 21extends to the arm 9 of the bell-crank or short section 8, adjacent tothe pivotal point 10 thereof, while from the bolt 19, which unites theouter ends of the double straps 1616, another spring 22 extends to theouter end of the said arm 9.

A bracket 23 is secured to the building-wall 1 just below the line ofattachment of the. upper end of the awning 2, and a sheave 24 issuspended from this bracket, over which a rope 25 passes, one end ofthis rope being secured to the rod 4. at the front end of the awning andthe other end hanging down adjacent to the wall 1. Another rope, 26, issecured to this same bracket 23, and the lower end of this rope carriesa sheave 27, over which still another rope, 28, passes, one end of thislast-named rope being secured to the hereinbeforenamed long framesection 5 and the other end of said rope being fastened to the bolt 20,which unites the upper ends of the double strap 17 17.

29 is a rope on the outer end of one of the frame-sections 5.

The operation of my device will be readily understood from the foregoingdescription of its construction, taken in connection with theaccompanying drawings. Let it be understood that the awning is down,with the parts in the respective positions shown in Fig. 1. .In order toraise the awning, a pull is given upon the rope 25, and as the outerends of the long sections 5 of the frame begin to rise the shortsections 8, through the action of the sector-plates 6 7, begin to lower,(carrying the inner ends of the sections 5 with them,) this actiondrawing on the spring 21, through the double strap 15 15, until as thesections 5 approach a vertical position the said spring 21 begins toretract and draws the upper ends of the sections 5 over toward the wall1 until the parts are in the positions shown in Fig. 2, when the spring22, which was drawn out and under tension at the beginning of theraising operation, is fully retracted, owing to the near approach of theends of the arms 9 and double straps 16 16,

'29 given a sharp outward pull, and the long sections 5 will begin todescend by gravity, the

spring 22 being thereby subjected to tension and serving, to balance theweight of the sections 5 until the parts are again in the loweredposition. (Shown in Fig. 1.) As the frameseetions 5 begin to rise andthe sector-plates 6 7 to lower in the operation of raising the awningalready described the weight of said sector-plates will materially aidin raising the said sections 5, and as the sector-plates begin todescend they draw (through double strap 17 17) on the rope 28, thusaiding greatly in the raising of the said sections 5 and enabling thisto be done with much less exertion than if there were single instead ofjointed framesections, and this rope 28 continues to exert its pulluntil the frame-sections 5 stand at about forty five degrees, when therope 25 has a more direct pull, as the end of said rope connected withframe-sections 5 begins to get more nearly in line with the sheave 24,so that less force is needed to complete the raising of the awning, andthe rope' 28 is then slack, as shown in Fig. 2, and when said awning isagain lowered this rope 28 serves to steady the descent and balance theweight of the outer ends of said sections 5, which are thusloweredgradually and without any quick jerk.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an awning-frame, the combination of long and short frame-sections,terminating at their adjacent ends in toothed sector-plates, in meshwith each other and the other ends of said short sections beingpivotally secured to a stationary structure, and having angularprojecting arms; links connecting the said sector-plates; spiral springsconnected to said angular arms, and series of double straps pivotallysecured to the sector-plates of the long sections, and also connected tosaid springs.

2. The combination of long frame-sections terminating in toothedsector-plates at their inner ends; short frame-sections pivotallysecured to a stationary structure and having toothed sector-plates atone end, in mesh with the sector-plates of the long sections, andangnlar arms at the other end; links connecting the said sector-plates;series of double straps pivotally secured to the sector-plates of thelong sections; springs connecting certain of said double straps to theangular arms of the short sections; a transverse rod at the outer endsof the long sections; an awning permanently secured to said rod and tosaid stationary structure; a pair of sheaves suspended from saidstationary structure; a rope secured to said transverse rod, and passingover one of said sheaves; and another rope secured to one of said longsections, and passing over the other sheave, and then secured to anotherof the said double straps.

3. In an awning-frame, the combination with long and shortframe-sections, terminating at their adjacent ends in toothedsectorplates, in mesh with each other, and the other ends of said shortsections being pivotally secured to a stationary structure, of linksconnecting the said sector-plates, a sheave, suspended from saidstructure; a strap pivot-ally secured at one end to the lower end of theouter sector-plate, and a rope secured to the other end of said strapand passing over said sheave and then secured to the adjacent longframe-section, intermediate of its sector-plate and outer end.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two witnesses.

CHARLES H. HANSEN.
